If a product/lead/opportunity etc. changed/created by a technical user, then no value is filled for the field 'CreatedBy' or 'ChangedBy' or 'LastChangedby' in OData response.
SAP Cloud for Customer
Reproducing the Issue
Take example of Product BO:
Execute GET call: <Service URL>/sap/c4c/odata/v1/c4codataapi/ProductCollection
The OData returns the persons name of the related user. Technical users don't have an associated person and therefore no name, which is why no name is returned.
Hence, the possible way for customer is to check user UUID instead of Name.
This is the same behavior across other business objects like opportunity and product.
For Lead BO, customer should use "LastChangedIdentityUUID" instead of 'LastChangedBy' to check the UUID.
For Product BO, we add the CreatedBy/LastChangedBy UUID in Odata 2108 version.
